Windows - Movie info only shown when folder is highlighted.

I have recently converted from Mymovies.dk to XBMC. I'm still planning to use the mymovies.dk scraper.

All my movies are stored as MKV files, and each movie is stored in a individual folder (called the same thing as the MKV file and the movie).
When I browse through my old movies, everything is fine. When browsing and using for example list view, it will show the cover art of the movie. But when it comes to new movies, it will only show info when I highlight the mkv file (and not the folder).
Is this by design, or is something wrong ?

I can also see that XBMC does not add new XML and JPG files when I use the scraper. Is that correct ?
